Application filed fiprl Si, im?. Serial No. lalja Vacuum Systems7 of which the jfollowing is e specicntion.

My invention relates to ineens for `feeding liquid fuel from a. supply tank to e ce1 bureter of an internal combustion engine.

The principal object of tlie invention. is

to reise the liquid fuel from e.' lower point to a higher point so that the liquid may loe ed by gravity to` the engine from this higher point.

Another object of the invention is to lift the liquid .by a vacuum created 'by the action of the' engine.

A. further object of the invention. is to provide positive means for breaking tie vacuum when enough fuel lies reached tli receptacle-et the higher point, so es to permit the fuel at this point to feed to the engine by Gravity.

Anotler object of the' invention is toau tonintic4 lly re-creute the vacuum in tlie receptaclii when the seine is practically empty of fuel. l

Another object is to provide means for vcaneing an uninterrupted flow of fuel to the carbureter While the vacuum is set up and is causing the fuel to rise in the receptacle.

The invention also consists in cert-.iin other features of constructionend in the combination and arrangement of the several parte to `be hereinafter more fully described und specifically pointed out in the appended claims.

ln describing my invention in detail, rel erence will be. lied to the accompanying drawings, wherein like characters denote like or corresponding parts throughouttlie several views and in which:

Figure 1 is a longitudinal sectional vievv through the device. l

Fig. 2 is a section on line Qf of Fig. l, Referring to the drawings l indicates the receptacle, provided with ecover'Q and n.

conical rbottoni 2. This receptacle is connected with. the usual storage tank by means of the pipe 3 and the check valve 4. lt is also connected with tne earbureter by Ineens of the pipe' having a clicclt (l connected. thereto by the coupling 7. llie upper part of tlm-f` receptacle s .connected -rod 12 with it so 1 'l l tene manifold of tne engin the pipe 8 connecting .vitli the d need 2, said port i n communie trie' Willi a circul r port l0 opening into the i ln the conical qbottoni 2 i loco. coc il., is guide .rod ino-v y ,fui ed in the receptacle by ineens ci? e '"breoliet per end seid guide rod passes a guideor tlieseid rod eieeve nes an air port 2a therein7 communicating 'witlfi the interior of the receptacle s own.

At tine seme time the valve 19 linicovers the port 2% veo es to admit air into the receptacle and time breek the vacuum therein. This 1lwill allow ,the liquid to llo'w leyv gravity through. the

clieck 6 and .pipe 5 to the cerbureter. iis the level of inel in the receptacle lowers elle loet le drops. tliougii the rod ,l2 is held up -liy reason the emotion in. the port l@ acting located the bottoni. 2Q and at its uit against the valve 1S. When the receptacle is practically empty the counterbalanoe cup 1G strikes the stop 17 and by reason of the Weight of this cup with the fuel therein the rod l2 is lowered so as to uncover' the port l and close the port 2t. Thus the vacuum is set up again and the receptacle is again filled as before.

By reason of the vent 20, the fuel in the pipe 5 Will .continue to feed to the carbureter, though the valve G is closed, by reason of the vacuum in the receptacle, it being understood that there Will be enough fuel in the pipe 5 to run the engine until the receptacle is full and feeding of the fuel to the pipe 5 begins again. As will be noted, the conical bottom 2 forms a sediment ohainlber and this can be cleaned out `by means of the cock 11.

It is thought from the foregoing that the advantages and novel features of my invention will be readily apparent.

/I desire it to be vunderstood that I may make slight changes in the construction and in the combination and arrangement of thc several part-s, provided such changes fall Withinthe scope of the appended claims.

I claim as my invention:

1. A vacuum feeding system comprising a` receptacle connected to the storage tank and with the intake manifold of the engine to create a vacuum in the receptacle to cause fuel to flow into the receptacle from the tank, a rod slidably mounted in saidlreceptacleya. valve thereon controlling the eonneetion With the manifold, upper and lower stops on said rod, a lioat slidably mounted upon said rod, and a receptacle always containing fuel to constitute a weight connected to said float and slidably mounted upon said rod for transmitting movement ih said rod when the liquid in the firstnamed receptacle attains a low level and the second named receptacle engages with the lowfermost stop to move said valve away from the connection with the manifold', for setting up another vacuum.

2. A vacuum feeding system comprising a receptacle connected to the storage tank and with the intake manifold of an engine, a lioat in said receptacle, means operated by the float for controlling the connect-ion with the manifold, a valve casing secured to the lower side of said receptacle, a valve seat in said casino a 'ball valve. in said v. .w casing, an outlet pipe connected to the side .of said casing `adjacent the valve seat and connecting said receptacle to the earbureter, a vertical vent pipe secured to the top of said valve easing and having a valve seat to receive said ball valve when the receptacle is filled, and said valve seat of the valve casing being adapted to receive said ball valve While a vacuum is being created in the receptacle so as to open said vent pipe to permit free air to force the fuel in the outlet pipe into the oarbureter.

In testimony whereof I affix my signature in presence of two witnesses.
